電力電纜故障分析與測試
隨著社會的(de)(de)(de)(de)(de)不斷(duan)發展和進步，電(dian)(dian)(dian)(dian)力幾乎(hu)滲透(tou)到(dao)了社會生活的(de)(de)(de)(de)(de)各個方面(mian)，電(dian)(dian)(dian)(dian)力輸(shu)(shu)送也(ye)成為(wei)關鍵性的(de)(de)(de)(de)(de)問題。目前，按照(zhao)電(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)(de)(de)結構來分，電(dian)(dian)(dian)(dian)網(wang)可分為(wei)架空(kong)(kong)(kong)電(dian)(dian)(dian)(dian)網(wang)和電(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)網(wang)。雖然架空(kong)(kong)(kong)電(dian)(dian)(dian)(dian)網(wang)比(bi)較經濟(ji)，而(er)且容易(yi)發現(xian)故障(zhang)便于維修，但它要占用較大的(de)(de)(de)(de)(de)空(kong)(kong)(kong)間，又因其運行情(qing)況受自然條件的(de)(de)(de)(de)(de)影響較為(wei)明顯，安全性也(ye)受到(dao)一定的(de)(de)(de)(de)(de)限制。從(cong)設計和運行的(de)(de)(de)(de)(de)角度綜(zong)合考(kao)慮，電(dian)(dian)(dian)(dian)力的(de)(de)(de)(de)(de)輸(shu)(shu)送絕大部(bu)分都采(cai)用電(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)(de)(de)直埋式(shi)(shi)輸(shu)(shu)送方式(shi)(shi)。采(cai)用電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜直埋式(shi)(shi)輸(shu)(shu)送有許多優點，諸如占用空(kong)(kong)(kong)間小，受自然條件的(de)(de)(de)(de)(de)影響小，相對來講比(bi)較安全等。但是(shi)，這樣一來電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜故障(zhang)的(de)(de)(de)(de)(de)測試...
